Could be a failed aquastop or something worse. Please check the E-number again.....sg43t52gb doesn't seem right.

Does the machine reset and pump out water?

If it resets and then doesnt fill then you either have a failed inlet water valve
(rare) jug impellor(common) or a clogged up pressure chamber and transfer pipe(very common)

Can you hear a humming as soon as the machine is switched on?

If so you have water in the base(leak) which has tripped the safety float and then machine will continually pump out.

Let us know the outcome to the above and we can help some more....

The new E number is good. The rest is a process of elimination. Reset the dishwasher then pour a couple of litres of hot water in the machine & start a program to see if it drains ok. The first thing a dishwasher does is to evacuate the sour water remaining in the sump, if it doesn't drain properly it won't fill either (although fill failure can have several causes). If it doesn't drain properly check first for a kinked/blocked waste hose or a blocked sink spigot. If those are clear but it still won't drain than you'll have to remove the side plates/front cover & dig a little deeper, but we'll come back to that later. If it does drain ok move on to check the aquastop. Pull the plug first then follow the fill hose to the rear of the machine & remove the plastic insert to access the 2 spade terminals inside. If you have a multimeter check the resistance across them is around 2k ohms. You could rig up a test flex/plug & hotwire the valve to check if it functions or not. If you get flow when the valve is energized briefly then the aquastop is good. To save needless typing check out the above first then re-post if your issue still isn't resolved.
